Title: only escape && and || and don't escape spaces

Single &, | and spaces are not special characters according to the [Lucene docs](http://lucene.apache.org/core/4_10_2/queryparser/org/apache/lucene/queryparser/classic/package-summary.html#Escaping_Special_Characters).

I removed escaping these and added escaping && and || which are special and have to be escaped.
